Mumbai is high on Bieber fever. 40,000 people turned into a choir as pop sensation Justin Bieber kick-started his maiden India concert with his chart topping number Mark My Words from his latest album Purpose. Bollywood stars like Alia Bhatt, Arjun Rampal, Sonali Bendre and Arbaaz Khan were among the B-town beliebers who attended the concert.

The sweltering Mumbai heat didn't slow down the tempo one bit as 'Beliebers' from across the country lined up to watch Justin Bieber perform. NDTV spoke to some as they waited in the blazing afternoon sun for gates to open.

Justin Bieber flew into India in the dead of night for his Purpose concert and was welcomed by shrieking fans waiting outside Kalina airport in Mumbai where his chartered plane landed. Video footage shows the 23-year-old singer navigating the VIP lounge of the terminal, wearing shorts and a hoodie and clutching a bouquet of flowers. His security detail includes Salman Khan's bodyguard Shera, seen in a blue jacket, ushering Justin Bieber through the airport and outside to be driven in a Rolls Royce to a hotel in Lower Parel. Almost immediately, the crowd waiting outside erupts into cheers.
